SWIVEL PLANE SUPPORT AND HANDLE.

SPECIFICATION forming part of Letters Patent No. 636,983, dated Noveniber 14, 1899. Application filed At ta 22,1899- Serial No. 728,165. (No model.)

To aZZ whom it may concern.-

Be it known that I, OARL E. HANSON, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Swivel Plane Supports and Handles; and I hereby declare the following to bea full,clear, and exact description of the same.

yinvention relates to a device for suspending a plane within an operating-handle so as give it a universal movement within the support.

It consists of an inclosing frame, within which the plane is pivoted longitudinally, and a forked handle-,with means for detachably engaging and adj ustably engaging it with the sides of the frame, so that it has a free movement with relation thereto, the two motions providing a practically universal joint.

The invention also comprises details of construction which will be more fully explained by reference to the accompanying drawings, in which' Figure 1 is a side elevation of the plane. Fig. 2 is a plan View. Fig, 3 is a front end view.

The plane A is of any suitable and desired form, andB is a frame made of metal or othermaterial having an internal length and width sufficiently greater than that of the plane to allow the latter a free movement within the frame. The depth of the frame is somewhat less than that of the plane, so that the lower edge of the frame will stand at a little height above the surface upon which the plane is to operate.

In the rear end of the plane a socket O is fitted at a suitable height above the bottom and centrally from between the sides. In the frame B is fixed a pin D, the end of which projects toward the interior, and when the plane is to be introduced into the frame.

the socket O is fitted upon the inner end of the pin D. The rear end of the plane has a similarly-fitted socket O, and a pin D at this end is carried upon a spring-plate E, one end of which is fixedto the frame B and the other is so formed that it can be taken hold of and pulled away from the frame, the elasticity of the plate E allowing this movement. When thus pulled away,the pin D will be withdrawn sufficiently to allow that end of the plane to be entered into the frame until the pin is in line with the socket 0, when by releasing the spring E the pin will enter the socket. The plane will then be swiveled and freely turn able upon its longitudinal axis.

In the sides of the frame B are made holes F, extending longitudinally upon each side,- and these holes have pointed extensions f cut out at one side and adapted to receive the correspondingly-shaped pins G, which project inwardly from the handle-frames H. As here shown, the handle-frames are two in number, so shaped as to extend down upon each side of the frameB, and by turning these handles until the spurs of the pins G coincide with the slots f the pins can be entered into the holes F. Then when the handles are turned .into the position they will normally occupy these spurs, being out of line with the slots 3", will serve to lock the handles in place. The engagement of these pins may be madebefore the handles are secured together at the upper end, where they are curved toward each other and are bolted to a central handle I by bolts, as shown at h. This central handle curves upwardlyin such shape as to be conveniently grasped by the operator and has sufficient length so that the plane may be used upon the floor while the operator is standing or in other places which are not convenient to be reached with the plane in the hands of the operator.

By means of the longitudinal and transverse swiveling of the plane it will be seen that the face and cutting-blade of the plane will always maintain themselves fiat upon the surface which is being planed and that any irregular movement of raising and lowering or turning of the handle to one side or the other with relation to the face of the plane will in no way affect its truth with relation to the surface upon which it is operating.

By means of the disengaging attachments it is easy to remove or replace the plane at any time, and the series of holes F allow the handle to be engaged with the frame, so as to bring the pressure at any desired point with relation to the position of the cuttingblade.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a plane of an in- 2- ceases closing frame, pivot connections betweenthe inner part of said frame and the ends of the plane and a handle swiveled to the sides of the frame substantially as described.

2. A plane having socket-pieces fixed at each end in a longitudinal axis, an inclosing frame having a fixed pin at one end adapted to enter one of said sockets, and a movable pin at the opposite end to fit the other socket, and a handle pivoted to the frame and turnable transversely with relation to the swivelaxis of the frame.

3. A plane having sockets fixed in its opposite ends in its longitudinal axis, an independent surrounding frame having a fixed pin in one end adapted to enter one of the sockets of the plane, a spring fixed upon the opposite end of the frame having a pin fixed to its movable end, passing through ahole in the frame and adapted to be detachably engaged with the opposite socket of the plane and a handle pivoted transversely to the sides of the supplemental frame.

4. A plane having sockets in the ends, an independent surrounding frame wit-h fixed and movable pins adapted to detachably engage the sockets of the plane, a forked handle the sides of which extend upon each side of the supplemental frame, pins projecting inwardly from the ends of said handles, radial lugs upon the inner ends of the pins, holes made in the sides of the frame with notches corresponding with the lugs of the pins whereby the latter may be inserted when in line with the notches and form keepers to retain the pins when turned out of line with the notches.

5. A plane having end sockets, an independent inclosing frame having pivot-pins adapted to fit the sockets and about which the plane'is tnrnable on a longitudinal axis, a prolonged handle having the lower ends forked to extend upon each side of the supplemental frame, lines of pivot-holes made in said sides and swivel-pins by which the handle sides are detachably connected with either pair of said holes.

In witness whereof I have hereunto set my hand.

CARL E. HANSON.
